An object is dropped from a height of 150 feet. Its heights s at time, t is given by the equation s(t) =-16t^2+150 ,where s is measured in feet and t is measured in seconds.

Find the average rate of change of the height over the interval [1, 2.5).

O 1) -56 ft/sec

O2) 77 ft/sec

03) 56 ft/sec

O4) -35 ft/sec

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
